SCROLLINFO
The SCROLLINFO structure contains scroll bar parameters to be set by the SetScrollInfo function (or SBM_SETSCROLLINFO message), or retrieved by the GetScrollInfo function (or SBM_GETSCROLLINFO message).
typedef struct tagSCROLLINFO { // si
UINT cbSize;
UINT fMask;
int nMin;
int nMax;
UINT nPage;
int nPos;
int nTrackPos;
} SCROLLINFO;
typedef SCROLLINFO FAR *LPSCROLLINFO;
Members
cbSize
Specifies the size, in bytes, of this structure.
fMask
Specifies the scroll bar parameters to set or retrieve. This member can be a
combination of the following values:
Value
| Meaning
| SIF_ALL
| Combination of SIF_PAGE, SIF_POS, and SIF_RANGE.
| SIF_DISABLENOSCROLL
| This value is used only when setting a scroll bar's parameters. If the scroll
bar's new parameters make the scroll bar unnecessary, disable the scroll bar
instead of removing it.
| SIF_PAGE
| The nPage member contains the page size for a proportional scroll bar.
| SIF_POS
| The nPos parameter contains the scroll box position.
| SIF_RANGE
| The nMin and nMax members contain the minimum and maximum values for the scrolling range.
|
nMin
Specifies the minimum scrolling position.
nMax
Specifies the maximum scrolling position.
nPage
Specifies the page size. A scroll bar uses this value to determine the
appropriate size of the proportional scroll box.
nPos
Specifies the position of the scroll box.
nTrackPos
Specifies the immediate position of a scroll box that the user is dragging. An
application can retrieve this value while processing the SB_THUMBTRACK
notification message. An application cannot set the immediate scroll position; the SetScrollInfo function ignores this member.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
